This article describes junior high school students' literacy numeracy skills in solving story problems on algebra. The research was conducted at private-junior high school located in Batam with 25 female students' research subjects. The data were obtained through the literacy numeracy skills test and interview results, and then the data were analyzed using a qualitative descriptive study. The results showed that the literacy numeracy skills of 25 female students showed an excellent category with an average score of 84.7. Students with the highest score can fulfilled two to three indicators, while students with low score of literacy numeracy skills’ test only fulfilled one indicator. The unfulfillment of indicators is caused by student errors include: 1) Not writing known data information and asked, 2) Wrong in solving the problem, 3) Wrong when calculating, and 4) Not writing conclusions on the results of the answers obtained.

This study describes the mathematical processes in TIMSS (Trends in Mathematics and Science Study) to reflect issues. A descriptive qualitative methodology was used in this analysis as the research approach. The research allocated the respondent to the 6th grade students of Muhammadiyah 6 in the sub-district of Dau, Malang regency, East Java, Indonesia. Using a TIMSS 2011 test and interview, data was obtained. The results of the study showed that visual representation took place in both classes of high, medium, and low capacity. Students of high and low capacity conducted the symbolic representation process at the comprehension level, while students of medium capacity performed the symbolic representation process at the problem-solving stage. In addition, as they wrote topics, the writing of the conclusions was done by students who had high skill. Students who had medium potential when they wrote questions completed the writing of the conclusions. The students with a low level of skill wrote what was understood and asked about the issues.

The aim of this research is to describe and explore the statistical literacy of middle school students in solving the Trends in International Mathematics and Science Study (TIMSS) problems. This research utilized the qualitative approach, with the research type being descriptive-explorative. The research subjects consisted of 6 Grade 8 students from Muhammadiyah Middle School 6 of Malang in Malang Regency, Indonesia. Two students had a high mathematical ability, two others had a moderate ability, and the last two had low ability. The data analysis technique applied in this research was the interactive technique, composed of data reduction, data presentation, and conclusion drawing. The data collection for this research involved testing and interviews. The utilized test consisted of an adaptation of TIMSS for the materials of data and opportunities. Interview guidelines were used to support the data collected from the test. The research results indicated that low-ability, moderate-ability, and high-ability students were similar in that they were able to understand the problems. The difference among students of across different categories lies in data processing and data communication. Students with high mathematical abilities could process data and communicate them in detail, while those with moderate abilities could process data and communicate them but not in detail, and students with low abilities could only explain the mathematical problems.

Relational understanding constitutes students’ awareness of appropriate procedures to solve problems along with logical reasoning.  Itis pivotal to help students solve problems in mathematics. It is necessary that the teaching of mathematics be directed to achieve relational understanding. Accordingly, students are capable of solving complicated problems in mathematics. This current research aims at analyzing and describing relational understanding and the patterns of answering questions of the fifth graders on integer operation. This study used a qualitative approach with a case study as the research design. Further, three students belonging to the fifth grade of Elementary School in Malang City, Indonesia, were set up as the research subjects. A test was administered to measure the subjects' relational understanding. All collected data were analyzed using an interactive technique. The result has indicated that the highly-proficient student was able to show excellent relational understanding. Besides, it was shown that the fairly-proficient student could show good relational understanding. The lowly-proficient student was shown to be able to achieve only half of the holistic criteria set for relational understanding. The patterns of answering the questions demonstrated by all students in all levels included jotting down the models, completing the models, and answering the questions. The highly-proficient student understood the information and wrote it down. Whilst the fairly-proficient student understood the information without translating it into the written form. At last, the lowly-proficient student did not pronounce any signals of understanding of the information
